It's worth a try to see if 2D performance and battery life improve.

I've always enabled it on all my smartphones...
[Mate 8 General] :
Thank you mate! after i fully recharged my phone 2morrow i will test it. 20minutes with , and 20 minutes without :)

Thx for your tip :)
[Mate 8 General] loudog3114:
How are you using the phone, by the way, with over 9 days of usage? You must have it in airplane mode with wifi off during sleep, correct?

---------- Post added at 02:25 PM ---------- Previous post was at 02:22 PM ----------

I tried powersave - it knocks the performance down too much for me. Got a 40k in antutu with it.

---------- Post added at 02:26 PM ---------- Previous post was at 02:25 PM ----------

I ended up disabling wifi altogether, again. Now I am only using LTE, since I have an unlimited data plan. That change halved the usage over night.
[Mate 8 General] Goku1992:
This phone has amazing battery life, huawei is destroying the rest. Are you using powersave mode, greenify or is this "out of the box"?
[Mate 8 General] dannejanne:
Battery life is amazing out-of-box even in performance mode. No need to hinder the CPU.
[Mate 8 General] DarkSilentSC:
I'm also getting near 8 hours of screen on-time. But this test is done by leaving the screen on (at 50% brightness & smart mode) and basically do nothing on it? Browsing lots of websites via chrome, play games, watch MX Player videos, youtubing, etc. would cause battery drain down to about 5 hours. Let me try again in performance mode. I've never left the screen this long before which is quite stunning. Now only if someone can come up with CM13.... :P
[Mate 8 General] cathain:
I'm seeing some inconsistency with the battery. Every night when I go to bed I turn of wifi and mobile data. Some mornings when I wake up it has only drained by about 1% and then other mornings it has drained 10%?
[Mate 8 General] bluheart:
I am.quite happy with.the battery life about 7hours screen. Standby drainage was high, 9 to 12% with 103 firmware. With 162 firmware, the standby time has.been.taken.care.of with less then 2% drain.
[Mate 8 General] Eustachy_Kapusta:
6h SOT, 4,5 day uptime on battery; Huawei did really great job with this phone.
[Mate 8 General] Wartoon:
What the??? O.o
[Mate 8 General] bibiner:
Anyone can give their opinion on how big of a difference between smart and performance mode? Standby and daily use
[Mate 8 General] farzamirani:
hey i have the same problem too....i've bought a mate8 recently and it's battery drainage overnight is catastrophe.... about 10-15 percent within 8 hours (2:00 am to 10:00 am ). i've done everything possible and the battery is optimized and nothing obvious is running on background...

just the wifi is on whole night no locations no 4g and nothing else..... by the way my build number is b102 and no official update is available yet!

plz help me

Charged on monday evening (48h ago), listened to music every night, SOT 7h 30min, 15% left, amazing!

[Mate 8 General] Pfeffernuss:
An average of 15 hours SoT is not possible, obviously :cool:
[Mate 8 General] drexappeal:
I really didn't think that was ever realistic for any phone I would ever own. It's such an amazing feeling when getting close to 15% isn't a sign for me to need to find a charger ASAP. One of my first tests, after purchasing the Mate 8, was checking how long I could go with "regular" use, after hitting the 15% warning mark. I can't remember how long I actually went, but it was amazing. Had I used "ultra" mode, I'm sure it would've lasted me even longer. I still can't figure out why Huawei hadn't made a bigger push to offer this phone in the US, through one of the providers. I think it would've been an even bigger sell for them. Then again, maybe that's what they intend on doing with the P9 Max, which I am likely to swoop up, if it's anywhere close to what the Mate 8 currently offers me.

[Mate 8 General] mohammed fayed:
I'm on software version b103.. still didn't get an OTA update yet and downloading now the b162 update from here on xda to flash manually.. regardless, screen on time more than 9 hrs and was using wifi and gps and camera and played a few games too..

I can't say anything about the battery life.. it's just Amazing!

regarding the 8% battery here in the screenshot, I was outside and couldn't get my hands on a charging outlet.. and also wasn't using the ultra saving mode yet!
[Mate 8 General] Unknown-X:
The highest SOT for my Mate 8 is 7 hours. Just got this phone 3 days ago, and charged twice.
[Mate 8 General] MWD1984:
Hey people,

Got a new OTA update (NXT-L29C432B170) on my Mate 8 yesterday. Since the update I got a lot more battery drain, even during the night when everything is switched off (and on Ultra power safe mode)?! Anybody else experiencing this? When I check the app stats I see Android system apps is 32% draining. That's a lot right?
[Mate 8 General] dlorean:
I'm back to C432B152 and use C432B170 Kernel. For me battery life is worse than with B152 and disabled doze. Waiting for the next update, hope it will be better than the last one.

sigh, cant decide if i should update to c432b170, c10b172 or stick to my current l29 b162... only thing id like to have improved a bit is battery life, not content with the 7-9h sot im getting at the moment. funnily, l29 B133 was thus far the best firmware ive had with regard to battery life, i was getting 10-12h sot :D

[Mate 8 General] farzamirani:
i have the exact problem and it is driving me crazy. every one said after update it would get fixed. but i updated my firmware to c185b162 which is the last firmware for my region, but just a little improve in battery life but its not completely fixed. before this i had c185b103 which was terrible and i had about 20% drainage overnight(8 hours) but now after update it got better and i have 1% drainage per hour(about 10% overnight) and actually when the screen is off.i found that the problem is from android system that consumes most of the battery percentage as u said. but since i've not rooted my phone i cant use wakelock detectors to see which app is waking my cpu up. but obviously its something wrong with in android internal apps and services which don't let the phone sleep and makes the cpu awake frequently. but without root i have no hope to discover which of them.....

by the way i've tried every thing: factory reset,wiping cache, installing the ROM again and again but nothing worked;the android system uses cpu about 6 hours per full charge and consumes about 40-50% of the battery life(15000 m.Ah)....although the mate 8's battery is strong enough to work 24 hour for me but i'm sure if the problem is solve it would last for 48 hours.

i really beg for any help that survives me. it is really ridiculous when android consumes even more than the screen where are the google's xperts?!

and it's not just mate 8 owners problem i read in some forums that some note5 and s6 owners after update to android 6 have this problem too... it is clearly androids fault and something interesting is that some of the users dont experience this issue and are satisfied with their great battery life .

i really expect google to solve it with and official update.
[Mate 8 General] PrimuSSaintS:
Hello everyone!

I've got my Mate 8 for about 2 weeks now and the battery has been nothing short of stelar, at least compared to the 2h of SOT I had on my Huawei Ascend P7 (I'm so glad they god rid of the "Ascend" in their branding). Even though I'm happy with it, I'm far from the 8, 9 or even 10 hours that some of you have, so I was wondering what I could do to improve my battery life. Here are some more details:

Model: AL-10 (4Gb Mocha Gold version)

Build Number: C900B162

Average Screen on time: About 6 hours

Rooted: No

let's take yesterday: I woke up at 8 AM, unplugged my phone, listened to music for about ... 2 hours total, used quite a lot of whatsapp (basically the only app I used to communicate), I browsed a bit internet but didn't play; I was outside for a while so I had to put the screen brightness to 100% (it normally is around 75% tho). At around 9 PM I was left with 3% and had to plug my phone. Before doing it I checked my SOT and it was around 7 hours (give or take a minute). I do have 21 protected apps (so I'm sure to receive notifications of) and use rocket player (music - I can't live without a "genre" tab) nova launcher pro and google keyboard (just so you guys know that I don't really use stock apps).

Some questions I have:

1) I have the bad habit of forgetting to cut the wifi when I leave home, does it use a lot of battery even though it's not "in use"?

2) Does nova launcher use more battery than the stock launcher? I mean, can I get an hour more of SOT by going back to the stock launcher?

3) What are your secrets to get such amazing SOT stats?

Thanks a lot guys!!!

Edit: I tried to keep the screen brightness on auto today, and I got 4h42min of SOT and still have 49% of battery (which would mean I could have 9+ hours of SOT (I didn't listen to music, mainly browsed reddit and whatsapp)).
[Mate 8 General] fabilaaaan:
Hey guys i need your help. I just get only a DOT around 4 hours... GPS off, wifi on, mobile Data off and the battery Mode is on intelligent. Btw i am on c432b170 hope you can help me !
[Mate 8 General] fabilaaaan:
Is it normal, that the keyboard need 1000maH??? I have a lot of battery drain..
[Mate 8 General] jbmc83:
clear data and cache on the keyboard, that should fix the problem :)

[MENTION=5966440]PrimuSSaintS[/MENTION]: i can see uve found the problem urself :) running such a big screen at 75-100% the whole time drains a lot of battery! i got the same setup, al10 with b162 and i keep screen on auto brightness. bam u got urself 7-10h sot :) depending on what ure doing, of course...

wifi is negligible, u can basically leavy it switched on 24/7 and it wont eat any battery at all... nova launcher aint a problem either, so rest easy :)
[Mate 8 General] taita:
Hello There. I'm on B152 and its fantastic. Now receive The notification to update to B170. Is it worth it? How can i remove the"number 1" notification without update? Thanks

Not too shabby :good:
[Mate 8 General] icy20:

And yes, on Wifi. And that's funny exactly why? I'm at home so why not :rolleyes:

[Mate 8 General] farzamirani:
Hi

As I said before my problem is battery drainage overnight(or when the screen is off) about 10_12% in 8 hours. And the battery manger shows the android system as the first battery consuming app with about 50% off consumption even more than my screen. First I thought it is a wakelock problem which doesn't let the cpu to sleep and cause battery drain but I found something interesting. I recently have installed the system monitor app and it monitors the cpu usage...as my phone is not rooted so I cant install bbs. So I tried to find out my battery issue with help of this app. After monitoring my cpu usage overnight I understood that actually my wakelocks and DOZ mode are ok because the cpu was 98% asleep but the android battery manager shows 1.5 hour of android system cpu used time whereas even the WAKEUP LINE(wake up bar) DOESN'T SHOW ANY WAKE UPS while the screen is off.... actually I think the battery manger doesn't show the correct battery usage.

When I turn off my wifi the battery drain overnight stops and the battery drops 1% per 6_7 hours that is ok. So I think my problem is not android system which the battery manger shows as the first battery consuming app because my cpu is completly asleep overnight... actually the wifi it self is consuming battery although the wifi consumption in battery manger is just about 0.5% that seems unreal.

My question is it possible that the wifi over consuming shows it self in android system?

Plz some one answer me no body tace cares of my problem here

I am really disappointed.
[Mate 8 General] themissionimpossible:
It's difficult to know what apps you have installed and running...;)

If you can, restore the Mate to factory settings and start over with only basic apps installed just to verify if overnight you still have such a battery drain.
[Mate 8 General] bibiner:
If after factory reset problem still exist. Strongly recommend you to exchange for new device. Might a some component causing high electric drain.
[Mate 8 General] dlorean:
Many people post those results without stats and don't mention, that this is with wifi only. Other people see the results and think something is wrong with their device. The funny thing is, you buy a mobile device for 600€ and use it like a tablet, which you can get for 200-300€. In the final result, it is your matter what you do with your money. Think, most use their device for which it's intended, mobile use.

[Mate 8 General] Pfeffernuss:
Tablet I find too big.

As stated, just got the device, didn't leave home, played with it, indoors @ wifi only indeed.

Still very satisfied with the result, my G4 would never make this (max 5 / 5½ hours SoT).

Of course, when walking outside,in bright(er) light and on data, the result will probably be halve. Then again, posting results is useless anyway,due to too many variables to begin with.
[Mate 8 General] dlorean:
Right, too many variables. But if posting battery life results, then with stats and how you used it. Only Screenshot with the sot doesn't help anyone ;)

Yes it is exactly the same as if I mentioned that I charge it every 2 or 3 days. That doesn't say much on its own... One should mention other stuff unfortunately to be able to judge good/bad battery life...
[Mate 8 General] dannejanne:
This is a typical day for me. On WiFi both home and at work. Did a backup with TWRP also which is the drop in the battery graph. Some smaller charge spikes too when I had it connected to the PC a couple of times.

Mmmm but actually it really seems to be a software problem or malfunctioning of system servicess...when the wifi is off every thing is ok....and many mate 8 users have yhis problem ( android system high battery consumption even mire than screen). Even in this topic you can find some!

Hey the androis system is the first app consumption for you too.

Could you plz tell me how much mili ampers it takes?
[Mate 8 General] jibaipukima:
normally 9 or 10 hour ,better than iphone
[Mate 8 General] addyboss:
Mine handle 2 days with normal use, i mean using 3/4G data and Wifi at home.

But it´s advice to optimize the battery at the Bat manager, to kill all the programs running at the background...
[Mate 8 General] Pfeffernuss:
Right, that's not the reason I bought a 4GB phone for. Have added 30 apps to the protected list, might add more. It's lovely to click on something and it opens in a blink.

Otherwise I just could've bought a 512MB device and be done with it :good:

Hi everyone, yesterday after i installed B180, made a factory reset and installed everything again in case.Now it's so clear to say, notificaion issues goes away and obviously phone is more stable.But still i got 10% drain at night (only sync open), is this normal ? or how much do your phones drains in a night ? Also after i installed B180 Android System usage was like 30-40% for the first couple hours but when i woke up this morning and check it from battery manager, again it was 72% usage.Is this normal too ? My father has a LG V10 and when i check its Android System usage its only 5% percent.lol

Mobile data and wifi is always on but when i leave phone at nights i turn off both mobile data and wifi.Also I never use Wifi+.

Yesterday when i was installing B180 it has got 80% battery level and after installation B180 i get all my apps (nearly 20) and made all settings about phone, drained 10% at night and NOW i got 2.20h SOT and %59 battery percentage, thats nearly satisfying but this Android System usage makes me mad :/

Please help me about this, thanks.
[Mate 8 General] farzamirani:
I have the same problem as you.... u can read my previous post in last pages I have explaind about this issue...

I have 10_12% drain over night but when I turn off wifi it becomes normal and about 1_2% ...

But android system is always the first consumer with the most cpu usage....

If u read my post u will get some info...

Just I say nothing works reseting or cleaning partion or anything esle I have tried everything.

It is not normal at all and if it get fixed the batterylife really gets better

---------- Post added at 05:14 PM ---------- Previous post was at 05:07 PM ----------

Could you plz tell me the m.a and cpu used time of your android system.?!

What is m.a ?

Cpu used time 10.5h
[Mate 8 General] Pfeffernuss:
mAh value :good:
[Mate 8 General] farzamirani:
Yeah this is the exact culprit of mate 8 battery drain....this cpu usage is abnormal for android system. First I thought it would be wakelock problems but a found out that the cpu is in deep sleep whole night....

Another thing interesting is that when the wifi is off and I dont have any battery drop but still the battery manger shows a lot of m.A and cpu usage of android system!!!!

I guess the problem is the wifi connection itself.... even when I sleep with mobile data my battery drain is less than wifi!!! About 2%.

---------- Post added at 06:31 PM ---------- Previous post was at 06:30 PM ----------

I get better battery life on my AL10 on the Chinese roms. The international ones seem to drain my battery faster.
[Mate 8 General] icy20:
Hm that is interesting. I seem to be having good enough, for my standards, battery life with L29 roms. Imagine what will happen if I use al10 rom :P

I just can't tolerate chinese in some apps that's why I stick to L29 roms till now...
[Mate 8 General] farzamirani:
Actually I dont kno the exact culprit...but I want to say that you are not alone

Tomooroow I'll put some pics of my battery usage and you'll see that the androis system is the firts with the most consumption even more than screen....

The only thing we can do is to wait for next update because there is no way with stock roms maybe if we root there will be some hope but I dont wan to unlock my phone yet....

I hope that android or huawei fix this issue in next update. This phone is great and the battery is perfect...this is just an annoying bug.
[Mate 8 General] jbmc83:
its funny, ive actually had the opposite experience :) and thus far, B133 L29 was actually the most battery friendly, come to think of that!
[Mate 8 General] tucker2:
Yeah i have completely same thoughts and same problem.I dont want to root too for now but people are getting around 8-12h SOT with same phone/same rom/nearly same usage.This is really really weird and making me nervous about phone.I hope Huawei is know this issue and working on it for users.I'm waiting for your screenshots.
[Mate 8 General] ajsmsg78:
There arent too many apps in my roms with Chinese letters. Once u uncheck a few things in KangVIP there aren't any Chinese anything. :)
[Mate 8 General] farzamirani:
Hey friend

I myself get the 8_10 hours SOT with a little tricks too...

The note is that for getting high SOTs you should work with you phone constantly and not let it to go screen off a lot...because actually we waste battery at screen off not screen on(android system). So if you have a day that the phone is always in your hand surfing the net or plying light games or watching movies you'll get that SOTs. So if we dont use the screen alot the main portion of your battery drains in sleep mode( our current problem).so you can barely get 4_5hours SOT right?

Another thing is try ultra power mode at nights....aftter update to b162 my battery got better and when I turn off wifi or set in ultra mode at night I barely loose 2% in 8hours... (before that it didnt help as you)

Another trick that I use for myself is that I have installed automatic wifi app which turns the wifi off with screen smartly and turns it on with screen....so I dont loose alot at wifi( although actually it shouldn't be this way and wifi shouldn't consume battery a lot:( ).

I just suggest you to clean your cache partion once maybe it worked a little.... I tried it and battery 20% got better. For this turn off phone and press power on + volume down key until the phone turns on. Now you see the recovery page with volume up and down and power button select wipe cache partion and then restart.

Wait about a day and see if it is effective or not.

I think without wifi and other options at nights you must not loose this percentages and this method maybe help.
[Mate 8 General] ajsmsg78:
Double tap to wake consumes more battery as well. If you have it turned on and are getting worse battery life then that is also the problem.
[Mate 8 General] tucker2:
8-10 hours ! I never see these levels on my phone ^^

Yes, i'm not a heavy user at all and you may be right about that.Yes, max 5hours.

I have never tried ultra power mode since i bought this phone but i can give it a chance if i really need it in future.

When i was on B103 already i cleaned my cache partion and after i jump up to B180 i cleaned cache partion again after factory reset on B180.

And if we come to yesterday night, before leave phone, i disabled 3 options; Keep Wi-fi on During Sleep is setted Never, Mobile Data Always On is setted OFF and Sync is setted OFF too.With these little tricks i got %6 battery drain in 10 hours and that's good for now.Also when i check phone when i get up, Android System Usage was %59.Still high better then being %80.lol
